In ̄uence of vibration on mechanical power and electromyogram activity in human arm ̄exor muscles
The aim of this study was to evaluate the in̄uence of vibration on the mechanical properties of arm ̄exors. A group of 12 international level boxers, all members of the Italian national team, voluntarily participated in the experiment: all were engaged in regular boxing training. At the beginning of the study they were tested whilst performing forearm ̄exion with an extra load equal to 5% of the ...
متن کاملSkeletal Muscles in Fetuses
There are few reports comparing the muscle fiber morphometry between human fetuses and adults. Data on fetal and adult muscle fibers would be valuable in understanding muscle development and various muscle diseases. This study investigated human muscle fiber growth to clarify the difference between the facial muscles and skeletal muscles. The specimens were obtained from three (6-month-old) mal...

متن کاملAging of human skeletal muscles.
Normal aging in humans is associated with progressive decrease in skeletal muscle mass and strength (sarcopenia) which contributes to frailty and falls. The age associated changes in body composition result from lower levels of anabolic hormones, oxidative damage, neuromuscular alterations and a general decrease in muscle protein turnover. In this review we discuss the potential mechanisms and ...
متن کاملHormonal and Neuromuscular Responses to Mechanical Vibration Applied to Upper Extremity Muscles
OBJECTIVE To investigate the acute residual hormonal and neuromuscular responses exhibited following a single session of mechanical vibration applied to the upper extremities among different acceleration loads. METHODS Thirty male students were randomly assigned to a high vibration group (HVG), a low vibration group (LVG), or a control group (CG). A randomized double-blind, controlled-paralle...
